Minister for Public Health or Chief Medical Officer: who is right about e-cigarettes?

Who is right about e-cigarettes?

It is not often that Ministers and senior officials take such different public positions on important policy matters, but on tobacco harm reduction and e-cigarettes, English health ministers and Chief Medical Officer for England take a quite different view. The CMO is given a measure of independence and can speak out as they please, but this is on the tacit understanding that the CMO provides dispassionate, scientifically reasoned advice in areas in which they are qualified to advise – to speak truth to power if you like. But what if the CMO isn’t providing scientifically grounded advice? Let’s examine their respective positions…

The Minister for Public Health

According to the ASH Smokefree GB survey, around two million adults in Great Britain currently use e-cigarettes. A third are ex-smokers who have given up completely, and a further third are using them as part of a quit attempt.

While e-cigarettes are not completely without risk, they carry a far lower risk to health than smoking tobacco. A recent Cochrane Review found that e-cigarettes can help smokers to quit or reduce their smoking and the National Centre for Smoking Cessation and Training (NCSCT) advice to local stop smoking services is that they should be open to helping smokers who want to quit smoking with the help of e-cigarettes, especially in those that have tried, but not succeeded, in stopping smoking with the use of licensed stop smoking medicines.

This position reflects a cautious consensus among the credible experts and is evidence based. For example, the Royal College of Physicians which has been providing authoritative synthesis of the science on smoking since 1962, says the following:

The RCP recognises that electronic cigarettes and other novel nicotine devices can provide an effective, affordable and readily available retail alternative to conventional cigarettes. These innovations could make harm reduction a reality for smokers, as proposed in our 2007 report.

On the basis of available evidence, the Royal College of Physicians believes that e-cigarettes could lead to significant falls in the prevalence of smoking in the UK, prevent many deaths and episodes of serious illness, and help to reduce the social inequalities in health that tobacco smoking currently exacerbates.

The Chief Medical Officer for England

The CMO for England, Dame Sally Davies DBE in contrast has been very negative. In New Scientist in March 2014 she declared e-cigarettes as one of the three “biggest health threats” in the UK (along with poor diet and lack of exercise). In the Times in October 2014, she opined:

Vaping is promoted as an alternative to smoking but the chief medical officer is not convinced. “I don’t think the evidence is strong enough to say they do help people stop. They really ought to just stop.” In fact she worries that e-cigarettes may be encouraging non-smokers to take up the habit. “There is evidence from the States in children.”

Flavoured e-cigarettes should, she thinks, be banned. “I would like to see [e-cigarettes] regulated as medicinal products, so what you buy and what it says on the tin is what you’re getting,” she says. “At the moment you don’t know whether the dose is consistent from packet to packet, whether it’s high or low.”

There should also be more safety checks. “If they’re made as medicinal products then you’re going to have a high-quality product, one that won’t cause household fires. And they won’t have flavourings in them which, vaporised and volatile, may not be safe. Butterscotch is great to eat but if you inhale it, for susceptible people it can give you chronic lung failure.”

More should also be done to limit the way in which vaporisers are promoted. “My daughter showed me some packets in a duty-free shop and they looked very glamorous and very appealing. That does worry me.”

Who is right?

Who is right? The Minister for Public Health is right.

There is no science to back any of the CMO’s assertions, which we examine briefly in the paragraphs below.

On quitting. “They really ought to just stop” betrays a poor understanding of how this behaviour works, how hard it is to quit (and how many don’t really want to try) and how unsuccessful the various approved treatments are. They typically raise quite rates from 4% to 6% for NRT. The most comprehensive study so far of ‘real world’ use of e-cigarettes showed e-cigarettes were much more success at smoking cessation than the licensed products used in real-world settings [link]

People attempting to quit smoking without professional help are approximately 60% more likely to report succeeding if they use e-cigarettes than if they use willpower alone or over-the-counter nicotine replacement therapies such as patches or gum

Regular use of electronic cigarettes amongst children and young people is rare and is confined almost entirely to those who currently or have previously smoked.

In fact use of e-cigarette by kids who would otherwise smoke may be a reason to be encouraged. We do not know whether her daughter’s experience in a duty free shop has led her daughter to become a vaper or smoker. Unless it has, we are unsure of the point of this anecdote – it might simply confirm that kids do not just look at something and then do it. In fact, we see no value in the anecdote at all.

On the “evidence from the States in children” – in fact the evidence shows the exact opposite of a problem and makes the opposite point to the CMO. E-cigarette use has risen in teenagers in line with the growth in use among adults, but the effect has been an accelerated decline in smoking and all nicotine use (see chart). Adolescents who are likely to smoke are, for the same reasons, also likely to be interested in e-cigarettes (a so-called shared liability model). But if they use e-cigarettes instead, that is a great advantage.

On risks. There is a consensus that e-cigarettes will be at least 95% less risky than smoking – based on what is known of vapour and cigarette smoke toxicity – and the maxim that ‘the dose makes the poison’. In fact no material risks have been identified so far. Professor Robert West of University College London, Professor Peter Hajek of Queen Mary University of London, Professor Ann McNeill, of Kings College London, Dr Jamie Brown of University College London and Deborah Arnott, the Director of Action on Smoking and Health, put the relative risk in perspective: E-cigarettes – what we know.

From analysis of the constituents of e-cigarette vapour, e-cigarette use from popular brands can be expected to be at least 20 times safer (and probably considerably more so) than smoking tobacco cigarettes in terms of long-term health risks

On flavourings. It is a simplistic flaw to believe that adolescents are attracted to childish flavours – adolescents normally want to reinforce their adult status. The one study that has actually looked at flavourings and teenagers (US-based) showed they had minimal interest (rating their interest at 0.42 out of 10) in flavours and that the there was little difference between disinterest in different flavours – though with Single Malt Scotch and Classic Tobacco slightly in the lead [link][release] – two obviously ‘adult’ flavours. However, for adults trying to move away completely from tobacco use, flavours are extremely important in breaking the link. See for example: .

Conclusions: The results of this survey of dedicated users indicate that flavours are marketed in order to satisfy vapers’ demand. They appear to contribute to both perceived pleasure and the effort to reduce cigarette consumption or quit smoking. Due to the fact that adoption of ECs by youngsters is currently minimal, it seems that implementing regulatory restrictions to flavours could cause harm to current vapers while no public health benefits would be observed in youngsters

On medicine regulation. It is common for doctors to venture far beyond their competence, but the CMO cannot make a recommendation on a licensing regime without considering what the extremely high costs, restrictions and burdens of medicines licensing would do to the market as a whole, especially if it reduces the uptake of these products and continued smoking. That requires knowledge of costs, benefits and unintended consequences that the CMO is unlikely to have – see our 2013 report: Costs and burdens of medicines regulation for e-cigarettes for some insight into the issues. It would erect high regulatory barriers to entry at the product and firm level, and put a dramatic brake on innovation. It would leave the market with a few high-volume commoditised products with little of the variety and ‘buzz’ that is attracting smokers. The only companies likely to succeed in market where these products are licensed as medicines are the major tobacco companies (pharma has shown little interest to date). The problems that such regulation would address can be achieved by setting technical standards, or ignored because they are not actually problems.

On marketing. We have actually done well on this in the UK. The Committee on Advertising Practice (this sets the codes for the ASA to implement) upgraded its Codes in October 2014 to include non-broadcast and broadcast provisions on e-cigarettes. These strike a good balance between commercial freedom, responsible marketing and protection of children – the framework is similar to that used for alcohol. Unfortunately the EU directive will ban nearly all advertising from May 2016 – in effect protecting the incumbent cigarette trade from competition from entrants – the new much lower risk products.

On Butterscotch flavour. The CMO was badly embarrassed for claiming on TV that butterscotch flavour was causing chronic lung disease and had been withdrawn. It has actually attributed to cases of ‘popcorn lung’ in a popcorn factory in the US many years ago, following extremely high and sustained exposure. Some e-cigarette companies fearing adverse PR, of the type generated by the CMO, have voluntarily withdrawn it.

What should the CMO do?

I suspect the CMO won’t see this as a reason to retire or refrain from commenting in this field, so here are some constructive suggestions:

Concentrate on building trust. The CMO plays a critical role in society, especially in times of emergency – for example in a SARS outbreak. It is essential that the CMO retains and builds credibility and trust in their authority. If the post-holder allows it to lapse in one important area, the public will become understandably sceptical about pronouncements and advice in every area. The CMO

See the opportunity and get the risks in proportion. Like many experts in the field, the CMO needs to recognise the opportunity to completely reshape the market for recreational nicotine into one that is less harmful. It isn’t just about quitting smoking – 19% of adults are still nicotine users and concentrated in the poorest groups in society. For them, this could be a rapid way to improve their health and wellbeing and to improve their household economics. So far the risks at individual and population level appear to be minimal and many of the vaguely expressed concerns stated above have no evidential basis.

Grasp the unintended consequences of excessive regulation. CMO needs to recognise that the regulatory ideas she advocates will have profoundly negative unintended consequences – they all have the effect of weakening a competitor to cigarettes, protecting the cigarette trade and causing more ill-health than there otherwise would be. CMO needs to build this into her mental model of the interaction between smoking and vaping markets.

Seek briefing from real experts. It is unclear where CMO is getting these ideas from – but they are not serving government or the nation well. CMO should seek briefing from the UK’s experts in the field: for example Professor Robert West (UCL, runs all the smoking surveys) , Professor John Britton (Nottingham, heads Royal College of Physicians tobacco group), Lind Bauld (University of Stirling, advisor to Cancer Research UK)

10 comments to Minister for Public Health or Chief Medical Officer: who is right about e-cigarettes?

[…] irresponsible thing I have ever heard from a senior official in public health. And that’s a high bar. This statement will cause thousands of needless deaths if governments do actually follow her […]

Thanks for your ongoing activism. It’s making a huge difference in the UK, and worldwide.

Unfortunately, here in the US, dissent (i.e. telling the truth) about THR and vapor products has never been allowed for those employed at Obama’s DHHS, nor for hundreds of DHHS funding recipients (including many/most DHHS contracted state/local health departments and many dozens of so-called academic researchers funded by DHHS).

Rather, Obama’s DHHS (spearheaded by DHHS’ Bill Corr formerly of CTFK, FDA and CDC) has had a six year old policy to deceitfully misrepresent scientific and empirical evidence (especially their own studies) to confuse and scare the public about THR and vaping (as well as smokeless tobacco) in order to achieve their regulatory goal of banning all vapor products (again).

While we’ll never convince Obama’s DHHS to tell the truth about THR or vaping (or many other things), US Congress can amend the FSPTCA and can prevent FDA from banning e-cigs (that the agency’s proposed deeming regulation would impose) and the US Courts can reign in on FDA’s unethical, inhumane (and unlawful in my view) deeming regulation.

And of course, the next US President can rescind some/all of the deeming regulation in 2017 (when the proposed e-cig ban would actually go into effect).

This is GREAT. You didn’t miss a thing.
I always like your writing, and you really nailed it here.
It’s funny that UK is facing what the US would be facing if FDA hadn’t gotten shot down in their efforts to regulate vaping as medical.
So UK is trying to make vaping medicine, while US is trying to hand off our market to those who addicted and poisoned us before – Big Tobacco – but either way, they STILL don’t have to figure out whether this ADULT CONSUMER PRODUCT is a medicine or tobacco…..they just get to keep taking our money, and treating us the hateful way they still treat smokers….not to mention cutting off an adult smoker’s choice to use a healthier alternative than Big Tobacco will ever make, vapor or death stick. They added things to make the nicotine in cigarettes more addictive…and that’s the main reason I don’t trust Big Tobacco, lobbying against the more advanced vaping devices – not to mess with vaping if our gov grants an undeserved monopoly to them just so they don’t lose money and don’t have to think about such an important thing as ending smoking too hard.
People who aren’t corporations are, and have always been, the answer.
And the liars need to be held accountable for their health HARMING lies. And they ARE losing credibility, because, in the real light of real life, they sound like hysterical fools, not the health authorities they should be.
Thanks again. I loved your words.

Sally only has one idea “smokers should grow a backbone and just quit”
Sadly she actually believes that simple phrase is the complete answer.
With here demonstrable lack of interest or expertise on the subject, she should be barred from the discussion, regardless of what the plaque on her door implies about her professional competence.

The statetistical children from the Criminally Deceptive Creeps even paint an inflated picture. They lumped together all kinds of ecigs. With and without nicotine. There is a class of colorful, cheap, disposable vape sticks (sometimes called “e-shisha”), that might appeal optically to children. But they usually don’t contain any nicotine. How many of those were counted?

The utterences of the CMO are almost verbatim the same bovine excrement that keeps hitting the german media fans. Spouted by Frau Pötscke-Langer, the Oracle of Heidelberg, Führer of the WHO collaborators.

Unfortunately all our officials seem to be faithful devotees of her church of healthism. They don’t bother to listen to any word some heretic vapers may say.
